I deal with the acquisition of physical data.
I would copy the partitions residing in dev / block / mtdblock on my laptop and mount them to see the content "offline."
I try to copy the partition with the command
"dd if = / dev/mtdblock/mtdblock1 of = / sdcard / data.dd bs = 2048"
but I have this error:
"/ Dev / block / mtdblock: read
error: I / O error
0 +0 records in
0 +0 records out
Transferred 0 bytes
in 0,004 secs (0 bytes / sec) "
It is not a permission problem on sdcard because I can not even copy the partition to another folder like / date.
how can I do this?
can anyone help me?
